General data logging

A GUI program Log book can automatically log compression, heating, and other records whenever new EDXD and/or radiography files are saved.

  1. Open ‘Log book’ from desktop shortcut.

    log_book_start_screen
  2. File ‣ New log

    log_book_new
  3. Next to ‘Log file’, click Browse… and choose the name for the log file, typically a new file in your own experiment data folder.

Logging can occur either automatically or manually. The program will automatically log a list of process variables (PV’s) and data file names each time a new data file is saved (EDXD, or radiography). Alternatively, click Record at any time to log the then-current experimental parameters. A time-stamped row of values will be appended to the log file each time.

LogBook allows recording any process variable (PV); however a pre-defined list of PV’s is stored in setup *.env file in the program’s resources directory.

The following default PV’s will be logged:
